Spreadsheet or app for planning a trip?

Why so many groups use a spreadsheet

Because it has no adoption cost. Everyone already has access, nobody has to sign up, and it works identically for all six people.

Because it is infinitely flexible. Any structure a group wants, it can build in five minutes, and no product decision made by someone else gets in the way.

Because it is genuinely excellent at the comparison problem. Four destinations across ten cost lines, with a total per person that updates as you change assumptions, is exactly what a spreadsheet is for and no travel app does it as well.

And because it is free and permanent. It will still open in five years.

Where it works well

The destination decision. Columns for candidate cities, rows for flights, accommodation, food, activity, and transfers, with a per-person total at the bottom. This is the single best use of a spreadsheet in trip planning.

The budget. Estimated versus actual, per person, with the shared and individual split visible.

The availability grid. Names down the side, candidate weekends across the top, and everyone marks yes or no. Crude and effective.

The packing and responsibility list. Who is bringing the speaker, who booked the transfer, who has the tickets.

• Destination comparison with a per-person total
• Budget: estimated versus actual
• Availability grid for choosing dates
• Who is responsible for what

Where it breaks

Mobile. A spreadsheet on a phone is close to unusable: horizontal scrolling, tiny cells, accidental edits, and no sensible way to see one day. Since the trip happens on phones, this is decisive.

Geography. A cell containing a restaurant name tells you nothing about where it is. There is no map, no travel times, and no way to see that a day zigzags across a city.

Notifications and change. When one person changes the plan, nobody finds out. A spreadsheet has no way to say the ferry time moved.

Structure over time. Spreadsheets accumulate: three tabs become nine, two people build competing versions of the same table, and by week three nobody knows which one is current.

The last-day problem

The specific failure mode is this: the group plans meticulously in a spreadsheet for a month, and then on the trip nobody opens it.

It is hard to read on a phone, the connection is poor, the relevant day is buried, and it is faster to ask the person who made it. So the plan lives in one person head, that person becomes the tour guide against their will, and the spreadsheet stops being updated on day two.

That is not a failure of planning, it is a failure of format. The work was good and the container was wrong.

A workable hybrid

Use the spreadsheet for the phase it is good at: availability, budget comparison, and choosing the destination. That is the analytical phase and it happens at a desk.

Once the destination and dates are fixed, move to something that works on a phone for the day-by-day plan and the bookings. That is the operational phase and it happens on the move.

Keep the spreadsheet as the budget record if the group likes it. Money reconciles well in a spreadsheet and badly in a chat.

The one thing to avoid is maintaining both as the plan. Two sources of truth is worse than either one alone.

• Spreadsheet: dates, budget, destination comparison
• Phone-friendly tool: the day plan, bookings, and what is next
• Never maintain both as the live plan
• Screenshot the essentials before travelling regardless

If you are staying with the spreadsheet

Make one tab called Today, or per-day tabs, so there is something readable on a phone.

Freeze the header row and keep the columns narrow enough to fit a phone screen.

Put the accommodation address, the flight numbers, and the emergency contacts at the very top of the first tab, where they can be found in five seconds.

And set edit permissions deliberately. A shared spreadsheet with six editors and no structure is a good way to lose a column on the day before departure.
